Calisphere exceeds half a million items!

“The deeper you look, the more you’ll discover.” Today, the Calisphere motto rings particularly true, as we celebrate the growth of the collection to over half a million items! (Or 530,711, to be exact.)

Recent additions include the Gold Rush Life collection from the University of the Pacific, which contains correspondence, diaries, and other primary source materials revealing the daily lives of individuals during the California Gold Rush; photographs, news clippings, postcards, and programs from the 1910 Los Angeles International Aviation Meet, contributed by CSU Dominguez Hills; and over 3,000 audio and video recordings from several institutions statewide, digitized as part of the California Audiovisual Preservation Project.

Calisphere’s new metadata infrastructure has made it possible to aggregate and provide access to more digital content than ever before. The chart below shows the amount of items on Calisphere since 2010. As you can see, the site has grown exponentially since its re-release this past fall. And the trend is set to continue, as more institutions sign up to have their collections harvested and aggregated by the site.
